I just picked up a Samsung Galaxy S II 4G to upgrade from my Motorola Triumph. One of the first things I noticed is how poor the WiFi signal is of the SGS2 compared to the MT. Sitting about 6 feet from the router side-by-side the MT next to the SGS2 shows the MT has much better WiFi signal strength. I used WiFi Analyzer to compare the signals. In fact, on the MT I can pick up distant WiFi signals coming from my neighbors however the SGS2 doesn't see them at all. I do note that if I hold the SGS2 by the top corners the reception is better. It would appear to me that the SGS2 has an antenna problem or the power level of the radio is poor. I Googled this issue and noted that many, many, many folks are reporting the same problem. I have not noted any solution to the problem. I'm starting to think this must be a hardware issue otherwise I'm sure there would have been a firmware fix for this by now.
